Abstract
PURPOSE: To reproduce virtually distortion-free voice from the audio record which has recorded long term play by changing over the number of revolutions of the disc to a low speed at the audio reproduction and further using the one which has recorded audio information by a PCM system.
CONSTITUTION: The signal which has been sent to a circuit for reproducing only the audio information through a switch 84 converts the digital information having been recorded by a PCM system and being reproduced from a disc 1 revolving 15 times per second to analog signal with a D/A converter and this is then put in an amplifier circuit 10, whereby the input signal to a speaker 11 is obtained. Next, to use a piecture audio reproduction record, the signal is sent to a picture audio reproduction circuit 12 by the switch 84. The circuit 12 is a video disc FM signal demodulation circuit and the signal demodulated therein is inputted to a television set, whereby the exactly the same picture as general television pictures may be obtained
